Hi Chris,
Hope this 3 patches only need to apply, if any other patches missing please let
me know.
https://issues.apache.org/jira/secure/attachment/12590105/MAPREDUCE-5351-2.patch
https://issues.apache.org/jira/secure/attachment/12590672/MAPREDUCE-5351-addendum-1.patch
https://issues.apache.org/jira/secure/attachment/12604722/MAPREDUCE-5508.3.patch
Also have downloaded the latest hadoop-1.2.1 version, while building jar I'm
getting snapshot version(i.e., hadoop-core-1.2.2-SNAPSHOT.jar) jars. Is these
because of some other changes are made in that version.
Hope this will not be a problem for updating in production environment.
Thanks,
